(Before you ask, he is one of my oldest X fursona I have, he will be upgraded soon, so don't get too comfortable with this picture, for now)

Name: Lucifer X
Species: Hybrid between a dog (Which is the choice for the person to decide.) and a a lizard of your choice. (Gecko, Crocodile, or Snake etc: ) Mostly a dog that has scales and furs at the same time and has a pointy tongue and lizard eyes as well.
Where his "X" symbol is: On his actual body on the front.
Height: 6'3" in normal height
Weight: Around 500 lb in normal weight
How big is his fursona body is: Well it is that round that his body (not just his belly) touches the ground, however he still can stand and walk around.
Ability: Inflate his body even bigger and changing the height and weight and the size limit has yet to be revealed. He also can deflate to make himself faster and agile while sacrificing his strength.
He also appears to be immune to certain diseases and poison as he is a hybrid of a reptile.
Personality: He doesn't really appear to be that intelligent as much, but his powers are the greatest strength of his. His personality is at times Serious and Confinement in what he does.
